More Over
According to DIN 4095, drainage layers must be arranged on ceilings that are to be covered with earth so that excess water can be safely drained away. As a rule, drainage layers are applied over the entire surface, not only under greenery, but also under pavements, terraces, play areas, etc. Floradrain® FD 60 neo, Stabilodrain® and Elastodrain® can even be used under pavements. With correspondingly high drainage elements, puddles can be bridged or the underside sewer system can be used for impoundment irrigation. This is of particular interest for intensive greening on zero-degree roofs. Drainage elements of the Floratherm® type even have a "general building authority approval" as additional thermal insulation.
